Module UI doesn't refresh after reinstall

Module Development
1

Hi,

I am developing a module for Ignition 8.1. The UI is a HTML page served by a Java class that extends the ConfigPanelclass.

I first install the module through the gateway by uploading it in the Modules page. Then, if I change the module code, rebuild the modlfile and reupload it again, the “backend” code has the new behavior, but the UI is still the same, even if it has changed.

Even using the Restart button in the Modules page doesn’t refresh the UI.

I have to docker restart the gateway for the changes to take effect. I’m wondering if there’s a way I don’t have to do that and instead see the UI changes without restarting the gateway.

Thank you.

Wicket, the backing web framework in 8.1 and prior versions, is full of weirdness like this. It may be possible to convince it to hot-reload via some system flags, but I've never tried.
